EUGEN STEIGER, OF Z'U'RICH, SWITZERLAND.

INKING-PAD.

To all whom it may concern:

Be it known that I, EUGEN STEIGER, a citizen of the Swiss Republic,residing at Ziirich, in Switzerland, have invented certain new anduseful Improvements in l'nking- Pads, of which the following isspecification.

A common disadvantage of ordinary inking pads lies in the fact that inorder to prepare them for lasting use they must be so abundantlysaturated with ink that while new they impart too much ink to the stamp,causing the latter to become clogged with ink, after a short time, andto give blurred impressions. Moreover, the ink is liable to graduallytrickle downward, so that the inking surface becomes dry and requires tobe reinked by hand, which usually results in some portions acquiring toomuch ink, and. others too little. The non-renewable inking surface alsobecomes frayed in time, so that after a comparatively short period ofuse clean impressions are no longer obtainable.

The object of the present invention is to provide an inking pad whichobviates these disadvantages.

The invention is illustrated in the accompanying drawing, in whichFigure 1. is a longitudinal section of the pad, Fig. 2 a plan view, andFig. 3 a crosssection.

In the chewing, (t represents a bed-plate, on which there is a softlayer Z) of rubber, felt, cork or like material; on the latter liesthe'ink cushion 0. This cushion consists of sheets of fabric 0 saturatedwith ink and alternating with sheets 0 of material which does not absorbthe ink, for example oiled paper, metal foil or the like, the sheets 0being placed between the sheets so as to isolate the latter from eachother. Over the ink cushion 0 there is a frame Z which is pressedagainst the cushion by nuts 6. The latter are screwed on to screws 9fixed to the plate 6, and are rotatably engaged with the frame (Z sothat the frame can be raised and lowered by rotating the nuts. Thescrews 9 pass through holes in the ink cushion, and the sheets 0 are cutaway at the corners (see Fig. 2) to enable the intermediate sheets 0 tobe taken hold of, for the purpose Specification of Letters Patent.

of removing the inked sheets, without touching the latter. The apertureof the frame can be closed by means of a cover f.

When, in the course of using the pad, the top ink-sheet of the inkcushion has become exhausted, the frame of is raised from the cushion 0by loosening the nuts 6, and the topmost sheet 0 together with theintermediate sheet 0 underneath it, is taken away, so as to expose afresh, unused ink sheet. Then the frame (Z is pressed down again on thecushion, by means of the nuts 6. lVhen all the ink sheets are exhausted,a fresh supply thereof can be placed on the bed-plate.

The intermediate sheets 2 prevent the evaporation of the ink and thedownward percolation thereof. Sheets which have been impregnated bymachinery can, therefore, always be used, having only so much ink as isrequired for the purpose of. furnishing sharp impressions.

Other means than the frame illustrated may be used for holding down thesheets, for example wire yokes.

hat I claim as my invention and desire to secure by Letters Patent ofthe United. States is:

1. An inking pad comprising a series of parallel inking sheets,non-absorbent sheets alternating with said inking sheets, a bedplatesupporting the pile of inking sheets and nonabsorbent sheets, screwsprojecting upward from said bed-plate, a frame resting on the pile ofsheets, and nuts rotatably engaged with said frame and said screws.

2. An inking pad comprising a base memher, a plurality of layers ofinking sheets supported by the said base member, and sheet ofnon-absorbent material intervening between each of the layers of inkingsheets, said non-absorbent material having portions which project beyondthe edges of the inking sheets.

In witness whereof I have signed this specification in the presence oftwo witnesses.

EUGEN STEIGER.
